I really hope bitcoin reaches $200 quick so I can get equipment in the bitcoin store for half price!
If bitcoin value doubles, then so does the market price per GH, all other things being equal.
So nope, aint gonna happen.
except that the market is 4 times too expensive (considering the 3$/Gh january offer), and that soon people will start understanding this. So if the value of a BTC does not change, the price of the mining equipment must.
